About the RP2350B-Dev-Board

RP2350B-Dev-Board is an open source RP2040/RP2350 PCB design by jvanderberg, published on GitHub. It is a 4-layer board measuring 77 × 20.8 mm, with 99 components from 26 distinct parts.

Its main chip is the C42415655, from the RP2040/RP2350 family. Other key parts include the HC-1.0-3PWT, C427602 and W25Q128. By type, the board carries 24 capacitors, 11 resistors, 4 ICs, 3 diodes, 1 crystal and 1 inductor.

It belongs with the dev boards & breakouts designs in this gallery.

From the project

RP2350B KiCad design

This is an RP2350B Dev board that breaks out all 48 GPIO pins.

It follows the original footprint of the RP2040 dev board, but adds 10 pins on each side.

It is not pin compatible with the original RP2040, though a version that shares the same pinout, at least for the first 20 pins on each side would be interesting.

The production files for JLCPCB are in the 'production' directory.

RP2350B-Dev-Board: common questions

What microcontroller does the RP2350B-Dev-Board use?

The RP2350B-Dev-Board is built around the C42415655, from the RP2040/RP2350 family.

How big is the RP2350B-Dev-Board?

The RP2350B-Dev-Board measures 77 × 20.8 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the RP2350B-Dev-Board?

99 components, from 26 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the RP2350B-Dev-Board design files?

From the jvanderberg/RP2350B-Dev-Board repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the RP2350B-Dev-Board design in my own project?

The repository has no license, so all rights stay with jvanderberg. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the RP2350B-Dev-Board without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
